Help

Hi I’m a depressed, sociopath I don’t have it bad but I don’t talk to my family a lot my dads becomes more of a dick each day I live in a new neighborhood where I don’t know any one my old friends left me behind and I’m just starting my first year of high school. Anyways I don’t know what to do because my sisters 16 has a car and is going to start working tomorrow I mean that’s cool but she’s the only thing keeping me sane so I don’t really know what to do anymore.
